WILLIAM F. MORGAN, OF COLLINGVVOOD, ONTARIO, CANADA, ASSIGNOR OF ONE-HALF TO ROBERT HUGHES, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 317,170, dated May 5, 1885.

Application filed October 16, 1884. (No model.) Patented in Canada October 24, 1884, No. 20,420.

T on whom it may concern.-

Be it known that I, WILLIAM FRANCIS MOR- GAN, of the town of Oollingwood, in the county of Simcoe, in the Province of Ontario, Canada,

carpenter, have invented certain new and useful Improvements in Bolts, (for which a patent was granted me in Canada on the 24th of October, 1884., No. 20,420;) and I do hereby declare that the following is a full, clear, and

r0 exact description of the same.

The object of the invention is to devise a simple and effective automatic door-lock, so

. arranged that it is practically burglar-proof; and it consists, essentially, of a series of bolts I5 operated by springs, and so arranged that the act of closing the door or doors causes the bolts to spring from the jamb of the door into its body, substantially as hereinafter more particularly explained.

Figure 1 is a perspective back view showing a d'oor-jamjo provided with two doors, a portion of the frame-work being removed to expose the construction and arrangement of the mechanism involved in the invention.

25 Fig. 2 is a perspective detail of the bolts with thelevers and springs for operating them.

As my improved door-lock is applicable to doors of every description, it is not necessary to describe the doors minutely or to specify the many kinds of doors where my lock will be specially applicable. It will be suffieient to say that for safe-doors it will be found in valuable, and it may also be advantageously used, either in whole or in part, for locking outside shutters; but, as before stated, it is not necessary to mention the many cases where it will be found serviceable.

A represents one side of a folding door, and B the other side. These doors are hinged in the ordinary way to the jambs G.

D is a bolt fitted-below and arranged to extend through the bottom sill of the door-j amb, andto extend into a hole (dotted in the drawings and marked a) in the bottom of the door A when the said door is closed. This bolt D, it will be noticed by reference to Fig. 2, is pivoted on the end of the lever F, which is pivoted 011 the fulcrum G, attached to the plateH, which plate forms a finish on the top of the bottom jamb of the door, and covers the recess formed in the said jamb for the reception of the levers and other parts shown in Fig. 2.

I is a spring, placed between the lever F and the'bottom of the plate H, so that by its 5 5 pressure the bolt D is made to protrude beyond the top surface of the plate H. When the door A is closed, the spring I permits the bolt D to recede, but as soon as the bolt comes opposite to the hole E in the bottom of the door A the said spring 1 forces the bolt D out into the hole, thereby effectually locking the door A until the bolt D has been withdrawn from the door A by the means I shall now describe. These means consist of a lever, J, piv- 6 5 oted at a to the door-frame, and one end of it arranged to connect with the lever F, while its other end has attached to it a vertical bar,

K, extending up the side of the door-frame and havinga rounded end, b.- 0 L is a bar fastened to the door A, and so ar-' ranged that when the doorA is closed the end of the bar L shall be in contact with the rounded end I) of the bar K.

M represents the end of a key provided to 7 5 operate the bar L. By this key the bar L is forced against the end b of the bar K, thereby forcing the said bar downwardly, causing the lever J to tilt on its pivot a and force up the end i of the lever 1*, to which it is attached, thus 8!) causingthe boltD to recede below the top surface of the plate H, leaving the door free to open.

It will be understood that several. of thebolts D may be similarly operated, and by it the strength of the fastening correspondingly increased. It will also be understood that the top of the door may be similarly provided with bolts D,operated in the same manner, and indeed I have so shown it in Fig. 1, where the 0 vertical bar K is duplicated, one bar extending upwardly tothe top of the door-frame,while the other bar which I have described extends to the bottom of the frame. I should also mention that I lay no special claim to the style of 5 key M, asits style may be altered to suit the various applications of the lock, the only point to be observed being that suitable means shall be provided to cause the bar L to act against an end of thebar K,when it is desired to open the door. XVith the view of simultaneously locking thedoor B by the closing of the door A, I'provide a bolt, N,which, as shown in Fig. 2, is connected to the lever O,which is pivoted, as shown,at the bottom of the plate H,and has on its end opposite to the bolt Nanother bolt, P,a spring,Q, being provided to cause the bolt P to remain below the surface of the plate H, while the bolt N protrudes above it. lhis latter' bolt, itwill be seen by reference to Fig. 1, extends below the bottom of the door A; consequently, when the said door is closed the bolt N is pushed down by it, thereby causing the bolt P to spring up into the hole made on the bottom of the door B, which has been closed previous to the closing of the door A. By this arrangement it will be seen that not only is the door A locked the moment it is closed, but the door B is simultaneously secured, thereby rendering the locking of the doors instantaneous and effectual.

The application of the bolts N and P to outside shutters will be exceedingly advantageous, and although both sets of bolts may be used for outside shutters, the bolts N and P may be in such cases used alone with great benefit. I should also mention here that the bolts N and P may also be arranged at the top of the door. Of course it is evident that other means than the bar K may be used for operating the lever F, or said bar may be omitted altogether and said lever actuated by pressing on the lever J with the hand or foot.

What I claim as my invention is- 1. The bolt D, attached to the end of the piv- 3 5 oted lever F, and arranged to protrude above the plate H, and the spring I, locatedfas specified, in combination with the door A,' having a hole, E, made in its bottom, and means,substantially as described, for operating said lever, substantially asffandifor the purpose specified.

2. The pivoted lever F, actuated by the spring I, and having the bolt D attached to it, in combination with' ia pivoted lever, J, connected to the lever F, and actuated by the bar 4 5 K, substantially as and for the'purpose specified.

3. The pivoted lever F, actuated by the spring I, and having attached to it at one end the bolt D, and at its other end the lever J, in combination with the bar K, having a rounded end, b, and actuated by the barL, substantially as and for the purpose specified.

4. The vertically-moving bolt N, attached to the vibrating pivoted leverO,and arranged to extend below the bottom of the door A, in combination with a vertically-moving bolt, P, attached to the other end of the pivoted lever O, and located below a hole made in the bottom of the closed door B, substantially as and 60 for the purpose specified.
